Numerical Requirements: Comment out "rogue" initial conditions

Description

Sylvia pointed out that Karl Taylors CMIP5 experiment design document does not always specify how users should set up the initial conditions for an experiment.
eg. 3.1 piControl has no i.c. specification.
but 3.2 Historical i.c. is from the piControl

We need to go through the requirement documents and comment out the initial condition numerical requirements that are not explicitly specified in Karls CMIP5 Experiment Design documentation
